How to Grow Foxglove Giant Spotted

Foxglove Giant Spotted

Digitalis purpurea 'Giant Spotted'

flower

Foxglove Giant Spotted is a dramatic biennial or short-lived perennial featuring tall spires of large, spotted tubular flowers in shades of purple, pink, or white with distinctive dark spots and contrasting throat markings. This cultivar grows taller than typical foxgloves, reaching 4-6 feet, and produces impressive flower displays that attract bees and hummingbirds. The downy, lance-shaped leaves form a basal rosette in the first year before flowering spires emerge.

Growing Conditions

☀️

Sun: Partial shade to full sun; 4-6 hours of sunlight daily; afternoon shade in hot climates

💧

Water: Moderate watering; keep soil consistently moist but not waterlogged. Water more frequently during dry spells and flowering. Reduce watering in winter dormancy.

📏

Spacing: 12-18 inches

📅

Days to maturity: 365-540 (flowers in second year as biennial; 90-120 days from flowering start to full bloom)

🌱

Planting depth: Surface sow seeds; press gently into soil. Do not cover, as seeds need light to germinate.

Soil

Type: Well-draining loamy soil with organic matter

Growth Stages

Seed Germination

10-14 days

Tiny seedlings emerge with cotyledons; very delicate and light-dependent

Maintain consistent moisture and bright indirect light. Keep soil temperature around 65-70°F. Provide air circulation to prevent damping off.

Seedling to Rosette (Year 1)

6-8 months

Plant develops fuzzy, lance-shaped leaves forming a low basal rosette; no flowering occurs in first year

Thin seedlings to proper spacing. Water regularly to keep soil moist. Protect from extreme heat and cold. Mulch lightly to conserve moisture and regulate soil temperature.

Flower Spike Emergence (Year 2, Spring)

3-4 weeks

Tall flowering spike rapidly elongates from the center of the rosette, reaching 4-6 feet

Install tall stakes for support as spikes can become top-heavy. Maintain consistent watering. Apply balanced fertilizer monthly. Remove any dead leaves at base.

Flowering

4-6 weeks

Tubular flowers open sequentially from bottom to top along the spike, displaying purple, pink, or white blooms with brown or burgundy spots and contrasting throats. Each flower lasts several days.

Deadhead spent flowers to encourage continued blooming. Support stakes should be secure. Continue regular watering. Monitor for pests and diseases.

Seed Maturation and Decline

3-4 weeks

Upper flowers fade as lower ones set seed; foliage yellows and may decline. Seed pods develop and mature.

Leave some flower spikes for seed collection if desired. Reduce watering as plant naturally declines. Allow seed pods to dry on plant before harvesting.

Harvest Tips

For cut flowers: Harvest spikes when lower third of flowers have opened, early morning when stems are firm. Cut at base with sharp knife and remove lower leaves. For seeds: Allow flower spikes to dry completely on plant; collect brown, papery seed pods when fully mature (late summer); store seeds in cool, dry place for next planting season.

Fun Facts

🌱 Foxglove gets its name from old folklore suggesting that foxes wore the flowers as gloves to muffle their paws while hunting chickens—though the actual origin is likely from 'folk's glove' or 'fairy's glove.'
🌱 All parts of foxglove, including roots and seeds, contain powerful cardiac glycosides that are highly toxic if ingested; even handling the plant excessively can cause skin irritation in sensitive individuals.
🌱 William Withering, an 18th-century physician, famously discovered that foxglove leaf extracts could effectively treat heart conditions, revolutionizing cardiac medicine and earning the plant its scientific genus name Digitalis.
